GB2 110118A 1
SPECIFICATION
A method and apparatus for the removal of solid components and aerosols, especially 5 soot particles from the exhaust gas of combustion engines
State of the Art
The invention originates from a method ac-1 0 cording to the preamble to the main claim. With dust removing plant, for example for power generation, it is known to conduct the dust through an electrostatic field so that the dust becomes electrically charged. The 15 charged dust is collected on the electric field plates (separating surfaces). The filter parts which form the separator surfaces are changed from time to time or the dust is removed from the separator surfaces by me-20 chanical forces, for example by a vibrating system and collected in a collector vessel. These plants have the disadvantage that they are of large size so that they can only be used with stationary plant and not in motor 25 vehicles.
Moreover, from the German Patent Application 30 41 070.9 a method for the removal of solid components from the exhaust gas of combustion engines is described in which two 30 partial streams are generated from the main exhaust gas flow from the combustion engine with the aid of a suitable separating device one of which streams is enriched with solid components and the other is thoroughly freed 35 from solid components. The separating device used with that method operates on the principle of swirl separation. The use of swirl separators has the disadvantage that at low flow velocities the exhaust gas is not sufficiently 40 freed of soot components.
Advantages of the Invention
As opposed to this, the method in accordance with the invention comprising the char-45 acterising features of the main claim and the apparatus in accordance with the invention comprising the characterising features of the sub claims 2 and 6 have the advantage that due to the combination of the electrostatic 50 separator with a mechanical separation, the size of the apparatus can be made very small. The soot components are separated very well both at high flow velocities and also at low flow velocities. Furthermore, it is an advan-55 tage that aerosols are also separated because they mix with the soot components on the separator surfaces. In that way, blue smoke and white smoke are also removed. Advantageous further developments and im-60 provements are made possible by the measures set forth in the sub claims. It is particularly advantageous that, with the aid of the corona discharge generated by the saw tooth emitting discs, the degree of separation is 65 increased.
Drawing
Two embodiments of the apparatus in accordance with the invention are illustrated in 70 the drawing and are described in detail in the following description.
Figure 1 shows a section through a first embodiment,
Figure 2 shows two possibilities for the 75 formation of the emitting discs,
Figure 3 is a section through the longitudinal axis of the second embodiment and
Figure 4 is a section along the section line l-l in Fig. 3.

Description of the Embodiments
In Fig. 1, a plurality of tubular housings 1 are arranged in a parallel bunch. The positive pole of a D.C. voltage source (not shown) is 85 connected to each tubular housing 1 wherein the housings 1 are earthed. The inner wall of the housings 1 form the separating surfaces 2. A plurality of emitting discs 3 which are connected through conductors 4 to the nega-90 tive pole of the D.C. voltage source (not shown), are arranged one below the other centrally with respect to the longitudinal axis of the housing 1. The emitting discs 3 have points, they can for example be made saw 95 tooth. Two embodiments of the emitting discs 3 are shown in Fig. 2 wherein a corona discharge at the points is referenced 20.
The exhaust gas to be cleaned is illustrated by the arrows 5 and is introduced into one 100 end of the tubular housings 1. The other end of the tubular housings change into a connecting pipe 6 to which the mechanical separator 7 is connected. Centrifugal or impact separators can be used, for example, as a 105 mechanical separator 7. The mechanical separator 7 has a first outlet 8 for cleaned exhaust gas and a second outlet 9 for the exhaust gas enriched with soot components. The method of operation of the apparatus in 11 0 accordance with the invention is as follows: The exhaust gas to be cleaned is introduced into the tubular housings 1. The electrostatic field lies between the separator surfaces 2 and the emitting discs whereby, due to the plural-11 5 ity of the emitting discss 3 charged negatively with respect to the positive separator surfaces 2, a virtual negative field area is generated. The exhaust gas flow to be cleaned is conveyed between the separator surfaces 2 and 1 20 the emitting discs 3. In so doing, by far the predominant majority of entrained soot components are charged negatively and consequently move towards the positive separating surfaces 2. There they give up their charge. 125 Impact ionisation contributes to a large extent to the charging of the soot components and aerosols. An illuminated glowing skin, the so called corona, is formed on the emitting discs 3 and leads to the corona discharge. The 1 30 electrons leaving the emitting discs 3 are
2
GB2 110118A 2
greatly accelerated due to the particularly strong electric field prevailing at that location. These primary electrons generate secondary electrons and secondary ions by colliding with 5 neutral gas molecules. A part of the electrons formed by impact ionisation are accumulated on the soot components and aerosols which are thereby negatively charged and are thus induced to be deposited on the positive separ-10 ator surfaces 2. The soot components and aerosols form a soot layer 10 on the separator surfaces 2, which continually increases. At a certain thickness which can be determined by the rough depth of the separator surfaces 2 or 1 5 by forming them as a grid structure, the layer 10 peels off flat and large soot flakes 11 are formed. The displacement of the soot layer 10 can also be controlled by a vibrating or blower device. The soot flakes 1 1 pass through the 20 connecting pipe 6 into the mechanical separator 7 in which they are separated from the exhaust gas in known manner. The cleaned exhaust gas arrives in the atmosphere through the first outlet 8 whereas the exhaust gas 25 enriched with soot flakes is returned for re-combustion through the exhaust gas feedback to the combustion engine which is required in any event for improving the exhaust gas. However, the soot flakes can also be collected 30 in special tanks.
As described above, the soot components in the exhaust gas are deposited predominantly on the separator surfaces 2. However, it is also possible for particles charged oppositely 35 to deposit on the points of the emitting discs 3. This must be prevented in all circumstances since otherwise a considerable weakening of the corona discharge occurs and with it the rate of separation of the electric filter 40 drops. Thus, the emitting discs 3 are formed in such a manner that the points can swing, excited by the vehicle vibrations and/or gas pulsations, and the deposits are shaken off thereby. For this purpose, the emitting discs 3 45 are made very thin, for example only 0.05 of a millimetre and only clamped in the centre.
A further embodiment is illustrated in Figs. 3 and 4 in which the electric filter and the mechanical separator are integrated with one 50 another. In this case, a whirl chamber is used. The whirl chamber 1 5 consists of a cylindrical tube 1 2 into which the supply line 1 3 introducing the exhaust gas to be cleaned enters tangentially. A perforated sheet metal cylinder 55 14 which carries on its periphery a plurality of emitting discs 3 lying one below the other, is located inside the cylindrical tube 1 2 and coaxially thereto. A coaxially extending dip pipe 1 6 which terminates open in the centre 60 of the whirl chamber 1 5 and of the sheet metal cylinder 14, is arranged at the end of the whirl chamber 1 5. An outlet 1 7 for the exhaust gas enriched with soot flakes is provided at the end of the cylindrical tube 1 2. A 65 diaphragm 18 which covers a portion of the end surfaces is arranged in front of the outlet 17 and spaced there from. The perforated metal cylinder 14 and with it the emitting discs 3 arranged thereon are connected to one 70 pole of a D.C. voltage source (not shown) and the cylindrical tube 1 2 is connected to the other pole of the D.C. voltage source.
The exhaust gas to be cleaned arrives in the whirl chamber 1 5 through the supply line 1 3. 75 Corresponding to the arrangement according to Fig. 1, the soot components and the aerosols are charged in the electrostatic field between the cylindrical tube 1 2 and the emitting discs 3 and deposit themselves on the inside 80 of the cylindrical tube 1 2 which forms the separating surface 2. When the soot layer on the separating surface 2 reaches a particular thickness, it is displaced whereby large soot flakes are produced. Due to the flow rotating 85 about the central axis of the whirl chamber 15, centrifugal forces act on these soot flakes which first of all drive the soot flakes against the wall of the cylindrical tube 1 2 and from there drive a boundary layer of a secondary 90 flow along the wall wherein the predominant portion of the soot flakes is guided between the diaphragm 18 and the cylindrical tube 12 to the outlet 1 7 and the remaining portion is guided along the diaphragm 18 towards the 95 centre. The cleaned exhaust gas arrives in the atmosphere through the dip pipe 16. Due to the corona discharge, there exists a so called electric wind which assists the centrifugal force and the formation of the secondary flow. 1 00 The outlets 1 7 for the exhaust gas enriched with soot can be connected to the exhaust gas return as in the first embodiment.
